Courts are becoming a new battleground for climate action. A new report by Columbia Law School’s Sabin Center for Climate Change Law and the UN Environment Programme (UNEP)reveals that climate lawsuits have surged to more than 3,000 cases across 55 countries, triple the number just a few years ago.
Of these, nearly two-thirds (1,986) were filed in the United States. Other hotspots were Brazil, the United Kingdom and Germany, each with more than 50 cases. Cases from the Global South still represent less than 10 per cent of the total, but are steadily growing.
